About The Position

Designs, implements, and optimizes components in distributed systems with an emphasis on scalability, resiliency, and operability. Delivers features and load/performance tests; leverages data plane platforms and distributed state tools for high-volume retrieval, storage, and processing; and reviews peers’ implementations for scalability compliance. Builds fault-tolerant paths through redundancy, replication, and automatic failover, applies recovery-oriented principles, and implements retries, circuit breakers, and timeouts. Proactively detects and mitigates issues through tests, alarms, dashboards, and telemetry; authors runbooks and participates in incident response and root cause analyses. Implements standard replication and synchronization, develops automation and infrastructure-as-code for troubleshooting and maintenance, and applies advanced security controls while ensuring change, compliance, and documentation standards are met.

Responsibilities

Implement and contribute to distributed-system components that support horizontal and vertical scaling, including through distributed state management tools.
Optimize code and systems for large-scale data processing.
Implement scalability requirements for assigned components and review team members’ implementations.
Use data plane platform components for large-scale data retrieval, storage, and processing.
Implement performance and load testing.
Collaborate with the team to build fault-tolerant components that withstand in-service updates through redundancy, replication, and automatic failover.
Apply recovery-oriented computing principles to design components that handle service disruptions.
Implement retries, circuit breakers, and timeouts to address network unreliability.
Implement tests and alarm configurations to proactively detect and address issues and failures.
Support failure recovery by drafting and executing runbooks and operational procedures.
Build and customize dashboards, telemetry systems, and alerting mechanisms to monitor component health.
Design and implement functional requirements and testing for assigned features in an existing system.
Implement fault-injection and brown-out test scenarios to evaluate system correctness.
Implement data replication and synchronization techniques to maintain data integrity and availability.
Diagnose, debug, and resolve system component issues to support ongoing operations.
Implement strategies to prevent interruptions and resolve issues without customer or user maintenance windows.
Design and implement automation scripts and tooling for operational troubleshooting.
Participate in operational support rotations, incident response, and root cause investigations.
Apply advanced security measures, including encryption and access controls, to protect data and applications in multi-tenant environments.
Implement plans to continuously improve security.
Help ensure cloud infrastructure complies with relevant industry standards and regulations and that documentation is up to date.
Maintain automation scripts and tools, including infrastructure as code, for managing cloud infrastructure.
Follow change management plans for application patching, updates, and rollbacks.
Track timelines with minimal supervision and complete work in a timely manner aligned with project requirements.
Prioritize and adjust work as resources or timelines change, with some guidance.
Collaborate across teams, align expectations, understand stakeholder and customer needs, and build effective partnerships.
Identify and address standard and non-standard issues independently, escalating more complex issues as appropriate; analyze information from multiple sources to troubleshoot errors and contribute to knowledge sharing.
Build knowledge and skills, stay current with industry trends and best practices, use feedback and training, and contribute to continuous learning and knowledge sharing.
Recommend process, protocol, and workflow improvements, and seek team input on alternative approaches.
